AUTOMATIC TELEGRAPH-TRANSMITTER.

Specification of Letters Yacent.

Patented May 6, 1913.

Original application filed June 17, 1909, Serial No. 502,785. Divided and this application filed June 2, 1910. Serial N0.564,587.

To all whom it may concern Be it known that I, LOUIS MAXWELL POTTS, a citizen of the United States, residing at city of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Automatic Telegraph-Transmitters, of which the followin is a specification.

This invention relates to that class of automatic telegraph transmitters in which the control is effected by a sending blank on which the information appears in lines of code perforations, embossments or the like, and is characterized especially in that the sending blank itself controls the selective movement necessary to bring about the operation of these perforations or the like.

The said invention is characterized further in that the same perforations or the like which act to efiect such selective movement also act to transmit signals corresponding thereto for .the purpose of effecting similar operations in other mechanism.

The said transmitter further embodies certainnovel blank feeding and lining mechanism, contact mechanism, spacing and carriage return mechanisms, all of which, together with other features, will be hereinafter more fully described and particularly pointedout in the claims.

The present invention was originally'embodied in an application for Letters Patent of the United States for telegraphy, filed by me June 17, 1909, Serial No. 502,785, of which the present application is a division.

Referring to the accompanying drawings which illustrate a specific embodiment of my present invention, Figure 1, represents one of the prepared controlling blanks in front elevation; Fig. 2, a diagram illustrating my improved system of code combinations on which the code charactersoi said blank are based; Fig. 3, a side elevation of a form of my improved transmitter; Fig. i, a longitudinal vertical section partly in elevation of said transmitter; Fig. 5, an enlarged fragmentary detail sectional view showing the transmitting blank passing on to the conveyer belts of said machine; Fig. 6, a top plan view of said transmitter with the lining and backing screws, together with their supports, and the top plate of the machine removed, to more clearly show the parts within the main body there-oi; Fig. 7,

The perforations on the controlling blank shown are arranged in accordance with a code based on a system of combinations over a system where each signal is retire impulse or an added line impulse, and an added and dropped Impulse simaltano oneletter tor another, and, an

numeral tor another sitions passing from the top to the bottom of the vertical row referred to, shall be called the a, b, 0, d, e, f, g, and'h positions, res actively. Each of such code positions is etermined by the vertical distance from.

each end of the row and by the horizontalosit-ion on either side of an imaginary line indicated by the dotted line a:-y, passin vertically through said zigzag row. Eac code character or signal is formed b one or more perforations occu ying a di crentone or combination of such positions. For e zample, for the letter A the perforations occupy the a and 0? positions; for the letter B the I) and f positions; for C, the l) and g positions, and so on through the al habet. lhe numerals, back, line look and Your other miscellaneous signals are, in the case shown, termed each by the comhination of three positions, For example, the code numeral 1 is formed loy perforations in the h, e and to positions; the back signal, which will he more readily understood later, is formed by perforations in a, h, and g positions, and the dollar mark by the d, e and f positions. The punctuation marks and space signal occupy hut one code position each. Such a system ozt comhinations possesses a decided advantage sented by one position only, or two po home only, or three positions only,in the signals to he transrnr are not long; and the perlorations when arranged in the code positions may he compressedinto a smaller vertical space, the latter losing an important consideration when the code perlorations come hetween lines or printed characters. Such a system has an advantage also over a system which uses all conihinations in a promiscuous way, as the employlog; of the same number oil positions or comhinations tor the ntrinerals as tor the char actors, in that it provides tor readily detecti r errors. This will he clear from a oomiileration ol the following facts: lllrwire which may he caused lay the line and the machine (not by the operator) are almost certain to result in a dropped line may; llheretore, it one letter were represented lay a certain combination oi"? two positions, and another letter hy one code position oidy, and a third letter lay three code positions, the dropping; ot a line would result in the. so u' adding all an impulse would result in suhstitotion oil a threeposition letter e two poeition letter, or a two'position or tor a one-position letter, When one lest; is substituted hy mists-lee tor another, or one one punctuation l m do marl; tor another, serious results may mission results merely in the substitution of a numeral tor a letter in a word,or a letter or some other signal for a numeral, which would be the case accordi to the s stem herein described, the mists e is sel evident. These blanks may be prepared either manually or automatically by an desired means, and since I do not herein clhirn such means, the some need not be described. It will be understood, however, that embossments or other forms of impression may he used in the place of said perforations, but perforations are preferred, and throughout the following description the code impressions will be referred to as" perforations.

Referring now to the mechanism controlled loy these blanks, this comprises, in the machine shown, electrical contacts controlled hy the perforationsin said lolanlr, a contact carrying carriage adapted to travel haclr and forth across the message hlanlr over said pertorations, conveying mechanism wherehy the message. blanks are led up to the proper point to bring the rows oil perforations into operative relation withsaid contacts, suitahle carriage retuiming mocha nisrn, and other parts, all oil which l shall now desorihe in greater detail. The pre pared hlanlie are led to the transmittertill through a vertical chute l, the lower end ct which is curved as at 2 so as to direct the lower edge of the lolanlr forward. chute is made last in any desired the top at the machine trams, which trams may consist simply oil two elongated plates 3 secured in any suitahle way to a hose Tho sides 3 at the machine shown orotitled each with an elongated flange w. ich is in turn provided with a narrow flange ill, the latter acting to support a removable plate 7. Passing under said chute and over the flanges 5 are two conveyor helts ll, consisting each at a strip oil flexible metal, or other suitable material. Made to each are spaced apart equally to register eriactly with the lnsohs h on the belts, so that there shall he ahsolutely no relative displacement or of? said hells on the drums,

ltllll a are provided with aoraes oil holes which.

nominee Also secured to said belts, at suitable intervals, are a series of hooks 15, each of which is adapted to extend through an opening in said belts. Each of said hooks is carried by a spring 16 consisting of a small strip of metal secured at its end opposite saio hook to the belt. Each of these springs is so bent that the normal tendency of the spring is to occupy a position at an angle to the belt as shown most clearly in Fig. 4, in which position the hook'secured to the spring is drawn back to the inside of the belt with very little, if any, of its length extending through the opening in the belt. r

The belts 8 in their travel bring the springs 16 into engagement with the upper side of. the flange lates 5, and when this occurs the said springs are forced by said plates into a position substantially parallel to the belt, when the hooks 15 on said springs, will extend substantially their full length through the belts. These hooks pass in this position under the chute 1 and engage the first two marginal perforations in the message blank in said chute and thereby cause the said blank to travel along with the belts. In doing so, the other marginal perforations of the blank engage the upwardly extending ends of the knobsl) which keepthe blank securely in the right position on the belts. (See Fig. 5 Where 17 represents the message blank). In this way the message blanksare fed forward to the operating position. The chute 1 is cut away slightly at its under side above the respective belts, to allow the hooks 15 to pass.

in the flange of each forward drum are two openings 18 (see Figs. 4: and 8) spaced apart diametrically opposite each other so as to register with each hook spring as it passes over the drum. As the successive hook springs reach these openings there is no longer anything to force the spring toward the belt, so that the springs jump back to their normal positions, thereby releasing the hooks from the paper or blank-which then passes from the forward end of the machine.

In order to more securely hold the paper down on the belts, there may be provided retaining plates 19 which may consist each of a metal plate or. bar made fast to the top of the machine and provided with a slot 20 to receive the knobs 9 and hooks 15. The lower face of these plates is near enough to the belts to keep the paper from flying up.

To keep the end of the paper or blank from passing upward as it emerges from the retaining plates, which may cause it to become disengaged from its hooks too soon, there may be secured to the forward end of each of the retaining plates a pair. of spring fingers 21. (See Figs. 3 and 7).-

These fingers are adapted to rest upon the topof the blank and press it down against the belts. I 1 The forward and rear drums are mounted respectively on two shafts 22 and 23, the former being journaled in fixed. bearings in the sides of the machine frame, while the latter is preferably journaled in two adjustable bearings 2%, adjustable laterally by means of screws 25 to efiect the proper ad.- justment ofthe conveyer belts. The forward shaft 22 carries the sprocket 26 fast on one end thereof, and this sprocket is geared to a sprocket 27 fast on the end of a counter shaft 28 (see Fig. 6) extending across the machine and journaled in the side frames thereof. Also mounted on the countershaft 28 and fast thereon, is alarger sprocket 29 which is geared to a sprocket 30 fast on the normally loose member of a clutch 31, mounted on shaft 32. This clutch comprises, among other parts, it nor mally rotating member 33 made fast to shaft 32 as by set screw 3% (see Fig. 12), and a normally stationary member comprising a stepped sleeve 35 loose on, shaft 32. The coupling of these members isefiected through a pin 36 mounted to slide transversely in the head of sleeve 35 and provided at one end with'teeth 37 adapted to engage teeth 38 on the face of an annular flange 38 on member 33. This pin 36 is provided with a recess 39, one of the Walls ofwhich has a cam surface -40. The bottom face of the pin near one end is recessed as at ll to receive flange 42 of a sleeve 13 slidable on sleeve 35 and normally forced to the right (Fig. 12) under the tension of coil spring as which engages said flange 42 and a flanged collar 45 fast on sleeve 35. In addition to pin 36, this clutch has three other pins 46, 47 and 48 similar in all respects to pin 36 except that they have no teeth. All, however, engage flange 4:2 in exactly the same way as does pin 36. Therefore, if any of these pins is moved laterally this moves pin 36. The reason for this will fully ap-- pear later. Said pins are preferably spaced equally apart so that the clutch rotates about a quarter of a revolution in each lining operation. This clutch is normally in theauncoupled condition; that is, the pins are forced back against tension of spring 44 so that teeth of pin 36 do not engage the normally rotating member 33. This is effected by the nose 49 on the upper end of a bell crank lever 50, engaging cam surface 40 of any one of the clutch pins, thus forcing it against spring 44:. The arms of this lever 50 are formed on a sleeve 51 loose on a counter shaft 52, and one of said arms is flexibly connected to a pivoted armature 53 of a magnet 54.- mounted in a cavity in a frame 55 which extends across the machine.

This frame may be supported at its ends in 78 on plate 73.v

any desired way. The armature 53 is normally held in the up position by spring 56 so as to force nose 49 into the path of pins 36, 46, 47 and 48. This magnet, lever and spring are not shown in side elevation, since they are identically the same as the magnet 157, lever 159 and spring 162 shown in side elevation in Fig. 4, The clutch shaft 32 is constantly driven by sprocket 57 made fast thereon and geared through sprockets 58 and 59 on a countershaft 60, to a sprocket 61 on the armature shaft of a small electric motor 62 or other suitable source of power.

It is very importantthat the shaft 22 be caused to stop the message blank exactly in the right place in feeding it up to the operating position, and that during the transmission, this message blank benot moved in the slightest degree. To meet these requirements there is made fast to the shaft 22 a star wheel 63 against the teeth of which is pressed a small roller 64, carried on the upper end of a ivoted arm 65 pulled toward the star w eel by spring 66. The teeth of this star wheel are so spaced that when roller 64 passes from one tooth to the next, the blank is fed up one line.

The traveling contact carriage comprises,

among other parts, a bracket consisting of two arms 67 extending from an integral sleeve 68, which is mounted to slide on a rod 69 mounted in upright supports 70 on each side of the machine. This rod is stationary and merely acts as a support for the contact carriage. Mounted in each of said arms forward of the rod 69 is a bushing 71 rotatable in said arms, and passing through thebushings 71 is a square shaft 72 which extends across the machine and is journaled in the supports 70. Mounted fast on top of the arms 67, forward of shaft 72,is a plate 73 having secured to. it, by means of depending arms 74, a plate75, the whole forming a rigid frame carried by and adapted to travel with arms 67 transversely of the machine. Mounted between the plates 73 and 75, for vertical movement, is a plate 76 (see Figs. 19 to 21), provided with two upwardly extending guide pins 77 made fast thereto and slidable in two vertical collars The plate 76 is supported at its sides by trunnions 79 resting in slots 80 (see Figs. 19 to 21) in the forward ends oftwo lever jms 81 mounted on the square shaft 72 and adapted to turn therewith. Mounted in the plate 76 for vertical movement therein, is a series of eight'pins 82 arranged in two rows of four pins each. (See Figs. 19 to 26). These pins pass, at their upper ends, through openings in the plate 73 which they fit loosely and at their lower ends through similar openings in plate 75, which they also fit loosely, that is, loose enough to slide .55 Between the plates 73 and 75 each of these pins is provided with an enlar ed portion 83 adapted to be engaged by t e plate 76. Directly.v beneath the line of travel of the pins 82 across the machine is a plate 84 perforated throughout the length of the travel of said pins, byopenings 85 which are arranged to register exactly with the pins in each position of rest of the contact carriage. In the top lan View, Fig. 7, a comparatively few of the openings 85 are shown, it bein understood that these openings extend t roughout the path of the pins 82. 'Plate 76 is normally held up in that position shown in Fig. 19 by means of springs 86 (see Fi s. 3 and 4:) carried on the collars 78 and he (1 between plate. 73 and stop-nuts 87 on the tops of the guide pins 77. The upper ends of pins 82 lie respectively beneath eight contact springs 88 which in turn are located just above a corresponding! number of contact springs 89. These contact springs are supported by being clamped between blocks of insulation 90 made fast to plate 73. In this way each spring contact is insulated from the other, and the contacts 88 are normally held up out of engagement vertical reciprocating motion is imparted to plate 76 through a cam 91 fast on shaft 92 of the spacing screw, said cam engagin a roller 93 on one end of a lever 94 made ast to one end of the square shaft 72. This spacing screw, shown most clearly in Figs. 4: and 7 is cut with a triple thread 95, which is removed for something more than two-thirds of its circumference, and these threads are adapted to engage corresponding triple threads 96 on a nut 97 mounted on two pins 98 fast in arms 67 of the contact carriage frame, the said nut being adjustable on said pins by means of adjusting screws 99. When the spacing screw is rotated, its threads engage those of nut 97 and thereby cause said carriage to beadvanced sleeve 102 (see Fig. 7 mounted loosely on the clutch shaft 32. This sleeve is made fast at its end opposite, the sprocket 101, to the normally stationary memberof the spac ing clutch 103. (See Fig. 6). This clutch is shown most clearly in the detail views Figs. 15 and 16, and comprises, among other parts, a normally rotating member 104 fast on shaft 32, and a normally'stationary memher 105 integral with or made fast in any suitable way to sleeve 102. The member 104 has an annular flange 106 provided with radial teeth 107 which are adapted to be engaged bythe teeth 108 of a coupling pin 109 mounted in member 105- for movement transversely thereof and forced in the direction of member 104 under tension of a spring 110 made fast to said pin and to member 105. The coupling pin 109 is provided with recess 111 and cam surface 112, and is in every way a duplicate of pin 36 of the lining clutch except that it is not recessed as at 41.

The coupling pin 109 is operated to uncouple the fast and loose members of this clutch by means of nose 113 of bell crank lever 114 which is adapted at times to project into the channel formed by flanges 115 and to engage cam 112 and thus force said pin away from the teeth 107. This bellvcrank lever 114 is loosely fulcrumed on shaft 52 and one of its arms is flexibly connected to the pivoted armature 117 of a magnet 118 mounted in a cavity of the magnet supporting frame 55, the said armature being normally forced upward under tension of spring 120 which forces the nose 113 of said lever toward the clutch. (See Fig. 6).

For. the purpose of returning the contact carriage to the commencement of its travel, I provide among other parts a backing screw which consists in the case shown of a raised spiral 121,0n a cylinder 122, extending-transversely of the machine and mounted fast on a shaft 123 journaled in the sides of the frame of the machine as shown. This spiral has a constant pitch except for'one revolution near one end where the pitch decreases as at 124 to zero in less than one revolution, and at this end the screw is pro vided with a flange 125 which acts as a stop for'the carriage. The spiral 121 of this backing screw is adapted to engage a small roller 126 rotatably mounted on a stud or pin made fast to a block 127 mounted on pins 128 carried by arms 67 andadjustable by screws 129 similarly to block 97 It will therefore be seen that if the backing screw is rotated in one direction travel will be imparted to the contact carriage through roller 126.

The backing screw is driven by power applied to sprocket 130. This sprocket, however, is not itself connected directly to the backing screw, but isfast on a sleeve 131 loosely mounted on the backing screw shaft 123. This sleeve carries a lateral pin 132 made fast to a collar 133 fast on sleeve 131. This pin 132 is adapted at times to engage a radial pin 134 made fast to a sleeve 135, slidable longitudinally on shaft 123, but held against rotation thereon by pin 136, enga ing slot 137 in said sleeve. The sleeve 135 18 provided with two annular flanges 138 be- 5 tween which extend the fingers 139 of an arm 140 forming an extension on a sleeve 141 mounted loosely on the spacing screw shaft. (See Figs. 7,17 and 18). This sleeve 141 is provided with a cam projection 142, which 55- fits normally into a correspondingly shaped ward under tension of spring 149.

recess'in a sleeve 143, made fast on the shaft of thespacing screw.- The sleeve 135 is forced in the direction of sleeve 131 under tension ofcoil spring 144. From this construction it will be seen that when rotation clockwise is imparted to the spacing screw shaft the cam projection, 142 Wlll ride upon the cam surface or sleeve 143, the sleeve 141 being caused thereby to be shifted laterally againstthe spring. This shifts sleeve 135 also in the same direction, thus removing pin" 134 from the path of pin 132. This disengages the' backing screw shaft from its driving sprocket 130, and leaves it free to be rotated by the roller 126 on the carriage, in the forward travel thereof. If the backing screw remained all the time geared to its power clutch, the roller. 126 striking the spiral 121 on the forward movement of the carriage would not only sto the carriage, 35 but the backing screw woul try to rotate the backing clutch loose member backward, hence it is essential that the backing screw be absolutely free while the carriage is pass- 'ing forward. .Directly after each spacing operation, however, the backing screw becomes coupled up to its power sprocket 130 by the returning of the sleeve 135, undertension of spring 144, to its normal position.

Sprocket 130 of the backing screw is geared to a sprocket 145 fast on an elongated sleeve 146 (see Figs. v6, 7) mounted loosely on the clutch shaft 32 and fast to the normally stationary member of the backing clutch 143. This clutch is substantially a 0 duplicate of the spacing clutch above de-, scribed and therefore need not be described in detail. The actuating nose 144 of this clutch is carried on the upper end of a bellcrank lever 145 carried by a collar 146-1 05 mounted loosely on shaft 52 (Fig 10). This bell-crank lever is operatedby magnet 147, having a pivoted armature 148 flexibly connected to the horizontal arm of said lever 145. This armature is normally forced up- This magnet, its armature and connection to lever 145 are the same in construction and arrangement as the magnet 157, its armature and connection to its bell-crank shown in Fi .4.

en magnet 147 operates its armature, thereby withdrawing nose 144 from the backing clutch and starting the carriage backing mechanism, a latch 150 engages a shoulder 151 (see Fig. 10) on the top of the backing clutch lever and holds said nose out of engagement with said clutchuntil released bya cam 152, on the contact carriage, engaging the upper end of'a lever 153 mounted fast on the same shaft 154 with latch and extendingu through the top of the'machine. The late 150 is raised by cam '152 against tension of spring 155, se-

cured tosaid lever 153 and to a pin 1'56 secured to the side of the machine. By this means the backing mechanism is automatically stopped as soon as the contact carriage reaches the end of its back travel. I

The message blank is fed up to the proper pointso that the first line of perforations will be in position to receive the contact actuating pins, by mechanism which acts to put the lining mechanism into operation and continue it in operation until the blank has reached the proper point. This operation will hereinafter be referred to as blanking.

In the transmitter, this mechanism consists among other parts, of a magnet 15? (see Fig. 41) provided with a pivoted arm-a-.

disk 161 simply acts as a stop to limitthemovement of the bell-crank lever in one direction. This lever is fast on a sleeve 163 which is loose on shaft 52 and is provided at one end with a lug 164 adapted to extend into an elongated recess in the end of sleeve 51 which carries the actuating lever of the lining clutch. Therefore, every time sleeve 163 is rotated in one direction. it carries sleeve 51 with it, thereby causing the fast and loose members of the lining clutch to become coupled and setting the lining mechanism in operation. The opening in which lug 164 works, however, is long enough a allow a certain amountof lost motion between said legend the sleeve 51,. so that when said sleeve is rotated in the regular lining operation, the sleeve 163 of the blanking device is not necessarily rotated. The necessary rotation is imparted to sleeve 163 to accomplish the above result when the magnet becomes energized and pulls down on its armature, causing its bell-crank lever to rotate said sleeve. For the purpose of holding this bell-crank lever in position long enough to bring the controlling blank to the proper place, the upright arm of said hellcrankis connected by means of arm 165, to

i a lever 166 fulcrumed at its lower end on a nosopas which the said arm is normally forced a Ward against said pin. Thev shoulder 1 1 then holds the lever 166102101: so that its roller 168 will not be engaged by either of the lugs 176 on the cam 169. The lever 166 acting through arm 165 will thus hold the bell-crank connected to armature 158 back. The lining shaft will, therefore, continue rotating until one of the lugs 17?, on a cam 178 fast on shaft 22 engages a, roller 179 jolirnaled on arm 172, thereby forcing said arm down and allowing lever 161) to be pulled back to the right by spring 1 55, since shoulder 171 is then below pin 170. This sends the backing hell-crank lever forward, and rotates sleeve 163 in such a direction that its lug 164: will allow sleeve '51 (see Fig. (l) to rotate and send the nose of the lining clutch lever into that clutch and thereby disconnect the loose from the fast member, stopping the lining mechanism from blank mg.

Whenever the contact carriage is sent back to the commencement of its travel it automatically feeds the controlling blank up a line, and when the machine performs the blanking operation herein described it automatically sends the carriage back to the beginning ofits travel as well as feeds the paper up. These operations are combined. in the present machine by the circuit connections of the lining, backing and blanking magnets, as will be fully described later on.

It is important during the operations of lining and backing that the spacing mechanism shall not operate. I This is ef fected by a locking" device located near one side of the machine and consisting, among other parts, of a latch 180 mounted on a shaft 181 as a pivot, and connected through a link 182 to a lever 183 fast on shaft 52. The end of the latch 180 opposite its pivot is provided with a shoulder which, when the arm 183 is rotated downward, is brought into the oath of a pin 1841 fast on the upright arm of the spacing clutch lever 114. Therefore, whenever levers 50 or 145 operate to start their respective mechanisms, they rotate shaft 52' and this rotates arm 183 downward, thus pulling latch 180 into the .path'of pin 18%, and thereby lockin g the spacing clutch against operation. To prevent jamniing, the arm 183 is connected to link 1182 by the pin and slotconnection as indicated,

the said slot beingv held downward against the pin by means of a. spring 185. Therefore, if the bell-crank leverof the spacing clutch tries to release itsnose 113 from said clutch while the latch is down, "the rotation downward of lever 183 at such time would merely result in extending spring 185. a

The lugs 176 on cam disk 17'? are's'o dis' posed that should the operation of lining normally cause the neat succeeding blanla to stop wi h its printed heading under the coira: in M a limited extent. This causes the nose 49 of the lining clutch to be Withdrawn from said clutch. clutch to be sent by spring 4-2 into engagement with the rotating clutch member 33,

the blanking, that is, to bring the prepared blanlr up to the operating position. When sleeve 163 was rotated by the energization of magnet 15?, the said sleeve was locked in its operated position through arm 165 actingin connection with the lever 160 pin 170 and lug 171 as described, allowing the transmitter belts to travel forward under power transmitted through the lining clutch until one of the lugs 177 engaging roller 179 releases 211111165 by lowering the lug 171. Whenrlhis releasing takes place the disengaging nose of the lining clutch will be allowed to fly back to engage one of the pins of that clutch and thereby uncouple the normally loose member from the fast member thereof. This stops the controlling blsnlt in the operating position Where the perforations corresponding to the first line rprinted matter (W270i) MPD.) lie in the path of the travel or the contact controlling pins 82. This first line of matter simply identifies the message according to the usage ct American commercial telegraphs and further than this forms no part of the invention. g When contact was closed at 21a the lin magnet 54 received current over the "tollowing circuit: conductor 210., wire joint 221i, magnet t, conductor contsct springs 223 and 224i, contact springs 225 and 220, thence through contact 214 back to negative main as traced above for magnet At the same time a circuit was completed through backing magnet lei? as :tol lows: conductor 220 wire joint 227 magnet idl -contact sprin, and and thence lunch to negativ tturn traced above for magnet 5 t. returns the contact car to the cot-nrnencement its travel in case was not; aiready there when hlanlr "placed in the machine.

The first thing that happens after the transmitter spacing shaft commences to rotate is that the lug 190 on the spacing clutch (indicated diagrammatically in Figs. 22 to 24) engages roller'192 carried by lever 19%, rocking arm 18? in a direction to bring together contacts 180. This sends a clearing impulse through the tongue-returning or back coils 206 of all the relays 205. This circuit may be traced as follows: from positive supply terminal 215 through conductor 220, thence through the back coil 206 of each of the relays 205, through contacts 180, thence by conductor 230 to the negative supply main. This sends the tongues of all the relays 205 to their back stop contacts, it any of the said tongues were at the time away from said contacts.

limrnediately after the operation of coin lug 100 to close contacts 186 '(see Figs 22, 23 and 24:) the cam 91 on. the spacing screw shaft operating on lever 9t causes plate 70 of the contact, carriage of the transmitter to be lowered. This allows the pins 82 corresponding to the f and 9' code positions, (the letter to drop throu h the perforations in the message blank with which they rcgis ter. in Fig. the pins shownthus other ated are not the f and g pins but, as shown, they illustrate the idea. By these pins ooseing through their periforutions they cause the two spring. contacts 88 and 8'9 shore them to be brought into engagement respettivcly with each other (see Fig. By closing contacts at these points circuits are closed through the forward coils of the y end relays Fig, 2?.

said pins from contact with said blank.

Then, as the spacing screw continues its rotation, its threaded portion will engage nut 97 on the contact carriage of the transmitter and cause the said carriage to be spaced up to the next position which will bring the contact controlling pins into the next transmitting position. After a short interval,

the spacing magnet will receive another impulse, causing the spacing screw shaft to rotate, and then those pins which are in line with the c, g and h code perforations, corresponding to the numeral 2, (the next character in the line) will drop through these perforations. The printer will then print the numeral 2, the operations being substanas described with the printing of the letter l except that in the case of the numeral 2, the c, g and h transmitter con tacts, the 0, g and it relays and the c, g and h printer magnets operate. The printer is thus caused to print the characters W279i It will be seen from Fig. 1 that immedictely following the numeral 5 in the first row or characters which we are now as suming to he those which are being printed, there is a word space. immediately under this space is a perforation occupying the code position to transmit the spacing signal. When this spacing signal perforation comes beneath the transmitter pin registering with it,the said pin will drop through said peri oration, allow the 0? contacts 88 and 82) of the transmitter to engage each other and these will act in conjunction with Z relay and the d printer magnet to complete the circuit or the printer spacing magnet, thich will cause the printer carriage to space up as desc ibed. The printing of the characters i ls-D. isthen carried on as described regard to the other characters of the line. When all the characters this line have been printed, the transcontact carriage automatically starts to the commencementof its travel, and the controlling hlank is fed up a distance of one line, bringing the perforations of the secline of characters into the path of the conpins. These operations are controlled hy'the combination of code perforations oc cupying, on the transmitting blank, the a, b and ,9 positions. These perforations will he seen in 1 immediately at the right hand end of the perforations corresponding to the first line W2795 MPD. on the controlling blank. When the contact controlling pins of the transmitter register with these perforations they will operate the a, b and g transmitter contacts, and a, b and g printer magnets 204. The effect of this will be to close the circuits through the lining and backing magnets 54 and 14:7 of the transmitter andthrough the a, b and g printer magnets The circuit through the lining-and backing magnets 54 and 147 thus completed may be traced as follows: from the positive supply main 215, through conductor 216, wire joint 221, ma net 54, conductor 222, contacts 223 and 224i, contacts 2'25'and 240 of the g (operated) relay, thence through conductor 241, contacts 242 243 of the b, (operated) relay, contacts Ash-245 of the a (operated) relay, conductor 246, brush 202' of commutator 195, brush 200 of sziid commutator, conductor 219, back to the negative supply main. The circuit of the backing clutch magnet 1&7, may be traced as follows: from wire joint 227, magnet'lt'l, conductor 24?, contact spring 225, and thence back to the negative supply main over the same circuit as traced for the lining magnet 54, the connections being so arranged that each time the hacking'magnet is energized the lining magnet is energized, thus causing the transmitter to automatically line each time that it hacks. The circuits of the magnets thus completed, pass through the tongue and forward contacts of the a, b and g relays back to the negative supply main, just as in the case of the printing;- of a letter, hence these circuits need not he traced over again. At the end of some lines, as for example, the third line of the transmitting blank Fig. 1, it is not necessary to go hack to the commencement of the carriage travel to commence a new line. in such a case the combination of perforations occuring right after John Doe, and repre senting the line combination operate the a, b and f transmitter contacts and these in turn operate the a, band 'f relays which in turn operate their forward contacts to send current to the c, b and f printer rnznqnets.

"lhese relays also operate to close contactthrough springs 24%, 245, 242, 2&3 and 228-223' sending current to the coils of the transmitter lining magnet 54 which operates its clutch and through this sets in operat-ion the lining mechanism of the transmitter.

At the end of the last line oi": the telegram Fig. 1, will be seen a combination of perforations occupying the a, b and h positions. This is the code arrangement for the signal which will cause the used blank to be led out of the machines (both transmitter and receiver and a fresh blank brought up into position.

saidrelay to close its forwardcontact, thus completing a circuit through the coils of magnet 267, which being thus energized releases the pin of clutch 252 thereby coupling the loose member of said clutch to the motor Q53. This causes the brushes 251, 258, 261 and 265 to rotate. When magnet 267 down on its armature, a circuit is comp eted at contact'271 through the back coil of rela 268, thus restoring said relay to norma Once in each revolution clutch 252 automatically uncouples the driving motor'253 from the brushes 261-251. ThlS is efiected by mechanical'means substantially the same as that employed inthe clutches of the automatic transmitter described, and therefore need not be further described. Should brush 251 arrive on contact 250 while brushes 269 and 272 are in engagement with conductor 274, the forward coil of relay 268 would re ceive negative current from dynamo 277, but this relay is so wound that current in that direction'through its forward coil does I not operate its'tongue so as to send it against 1 its forward contact.- The intermittent cperation of clutch 252 and sunflower mechanism controlled thereby is in no waylimited to automatic. transmission; that is to say,'

this mechanism may be used as well with manual as automatic transmission, and no claim 1s herein made for th1s feature, smoe it forms the subject of claims in said application of which this one is a division. At the end of each signal, brush 26,1 engaging segment 263 completes a restoring circuit, above referred to, which returns the tongue of the operated relays 205 to normal.

While I have herein shown and described a specific embodiment of my said invention, it will be understood that I do not limit myself to'this specific construction, since many modifications thereof may be made without departing from the true spirit of my invention. I
